I haven't worked with any of those, but I have worked with bar-code scanners, and the way they work is that they basically emulate a keyboard typing really quickly. You click or tab into the text field that the bar-code belongs in, and pull the trigger, and the code is inserted in the text field.

Assuming that you want the device connected to the client PC (rather
than the server) then you could have a problem accessing it from the
browser.
